NON-REFILLABLE BTTL'E.

T0 ZZ whom t may concern:

Be it known that I, FnANoisCo QUiN'rANo CUESTA, a citizen of the Republic of Cuba, and a resident of Habana, Cuba, have invented a new and Improved Non-Refillable Bottle, of which the following is a full, clear, and exact description.

This invention relates to bottle closures and particularly to the Atype known as noni'efillable and has for. an object the provision of an improved simplified arrangement which will be inexpensive in the manufactureV and which will permit the free flowing of fiuid from the bottle while resisting reilling of the bottle.

Another object in view is the provision of a closure member which is Connected with and forms part of the neck of a bottle and arranged so that there will be a movable valve and vai'ioiis guarding. means forv preventing the actuation of said valve except by the fiuid in the bottle.

A still further object in view is to provide a closure in which there is a@ valve for preventing refilling and guarding means which also act in the capacity of means forming an air check.

In the accompanying'drawing:

Figure 1 is a longitudinal vertical section through the upper part of a bottle and the neck, disclosing an embodiment of the invention.

Fig. 2 is a detail perspective view of a slightly modified form of valve member to that shown in Fig. 1.

Referring to the accompanying drawing by numerals, l indicates the bottle which may be of any shape and size and which is provided witha neck 2 formed with a reduced portion 3 whereby an annular shoulder 4 is presented. An annular ring 5 is arranged interiorly of the neck 2 and acts as a support for the cylindrical valve member (i, which valve member is cylindrical or tubular and open at the lower end.

. N car the upper end a plurality of apertures 7 are provided in the valve member (i through which will flow the fluid from the bottle 1 when the bottle is inverted by rea-y son ot the tact that the weight of the fluid will move the valve member (i downwardly and past the upper edge 8 of neck 2.against the action ot spring 9. Spring 9 has been shown as being formed from a single member and coiled at the outer end, but it., is evident that any form of spring could be Specification of Letters Patent. i Pgitndl Jun@ 12, 191K Application filed May 13, 1916.

used without departing from the spirit ci' the invention, the use of this spring being only for holding the valve member closed against the action of air and also to'insuie j the closing when onlypart of the fluid has been removed.

Associated with the neck 2 is an auxiliary neck 10 provided with'a 4dividing web 11 merging into a tubular member l2 which in turn merges into a round or disk-shaped easing 1B which casing is .provided with a number of apertures 14 facing towai'd the valve 6. The auxiliary neck 10 is provided with a hollowed-out part at the bottom fitting over the neck 2 -and resting on the iiange 4. This auxiliaryneck may be secured rigidly -in position in any suitable-V inanner, as for instance, by being cemented thereto. rl`he casing 13 is preferably made suiiciently large so as to approach the sides of the auxiliary neck 10 but leave an annular passage 15 through which the fluid may pass when emptying the bottle. 'When the bottle is in a horizontal plane spring 9 holds the valve member closed and also iininen diately closes the valve member when set upright after having been inverted, thus` preventing the entrance of any-l fluid into the bottle 1. In addition to these featuresit will be observed that by the arrangenientof the apertures 14 and the way the casing' 13 and tubular member 12 are formed, an-

air trap is provided in the space-16 which will assist in preventing the iiow of fluid ,and also which will assist thespring 9 in closing the valve member 6 in case it is attempted to force iuid into thebottle whileA in an inverted position.

In Fig. 2 a slight modiied form of valve is disclosed, in which it will be observed that the valve 6 is provided with a diskshaped membenl? which will fit in the neck 2 when in use and has connected therewith a plurality of pins 18 connected with .the ring li), said ring and pins acting as guides Jfor guiding the valve in its upward and dowiiwa rd movement. When the bottle is in an upright position the upper surface of valve G is flush with the upper edge 8 of the neck 2. but when the bottle is inverted the weight of the fluid will move the valve G' until the disk 17 is moved toward the tubular member 12 and away from the upper'edge 8 of neck 2, whereupon the Huid may freely flow into chamber 1G and from thence out yof the bottle. It will 'of cbiirse p be evident that the length of the tubular men'iher l2 may be varied without departing' from the spirit of the invention and also the other parts may be changed in size and rearranged within certain limits Without depariing from the invention.

What I claim is: l

l. In a hottie of the character described, a neck, a valve arranged in said neck, an auxiliary neck connected to the ir'st mentionefl neck. said auxiliary neck being formed with a guard arranged above said valve, Said guard being provided with an annular dividing web which merges into the auxiliary neck and into a lion which extends above and below the web, am a disk-shaped hollow member merging into the upper part of said tubular member, said disk-shaped hollow member having apertures facing said web.

2. In a bottle of the character described, a neck portion, a cylindrical 'valve member arranged in said neck portion formed With a closed top and an open bottom, the sides tubular sec? of said valve member being formed with a 25 plurality of apertures below the top, a spring rigidly secured at one end to said neck portion and formed with a coil resting substantially centrally of said top for resilently holding the valve member in a lowered or closed position, and means arranged above the valve anl the spring acting as a guard therefor. l

3. In a bottle of the character described, a neck portion providedvi-ith a projection, a valve member arranged in the neck portion and; normally restingfon said projection, said valve .member having a closed upper end and depending-'parts acting as guides, a spring connected to said neck. portioln andextending to near the center of said va FRANCISCO QUINTANO CUESTA.
